A REFRIGERATOR that works by means of fluid carbonic acid has been invented by Dr. Otto Liesegang, of Berlin. Through immediate gassification of the acid, which is held in a valve, a temperature of 80 degrees below zero is produced in the cooling apparatus resulting in a speedy freezing of ice or icecream. The main apparatus stands on the top shelf of the box at the right to permit use of the left side for storage purposes.

Shrill the wind and wild the night;
Spooks go prowling, black cats fight;
So set your spooky fears aside
And join us on a Broomstick Ride!

It’s hard to remember what life was like back in those dark days before the coming of the Egg-Master. The idea that people had to whisk an egg using a fork… simply barbaric.

Egg-Master

Anyone for homogenized eggs? This nifty gadget will do the job.

M. DEANE HARPER of Dunbar, West Va., has dreamed up a neat little gadget for homemakers. It’s the Egg-Master, a device which permits an egg to be beaten within its shell, eliminating the necessity of breaking the egg into a bowl and beating it with a beater. It’s fine for making omelets, mixing drinks and a host of other kitchen tasks. A machine shop instructor, Harper began his Egg-Master as a hobby and turned it into a profitable sideline.

Push-Button Telegraph center permits messages to be typed only once, on a “printer perforator,” at point of origin. When messages reach the center, a clerk pushes a button for the city of destination.

Fishy Idea dreamed up by amateur inventor Dr. Carl Omeron, right, looks like a spark of genius. This is it: Tie balloons to a live “Judas” fish (which you catch the hard way). Put Judas back in the water and he’ll lead the way to the whole school.

I’d wasn’t aware of this meaning of the word polygraph, though it actually makes more sense than the current definition.
